Synthesizer V
AI vocal synthesizer that turns lyrics and melody into lifelike singing, with a free tier and advanced Pro editing.
Synthesizer V is a top pick for natural-sounding AI vocals—the free version is capable, and Pro's cross-synthesis and automation are worth the one-time price. If you need realistic, controllable vocals for pop, EDM, or anime, grab it. The trade-off is a smaller voice library than Vocaloid and no live-performance angle.

Skip Synthesizer V if you need a live performance tool, a plug-and-play replacement for a human singer, or a fully free vocal solution with multiple voices—voice banks cost extra and the engine shines best in controlled studio workflows.
Additional voice banks are sold separately (typically $50–$100 each), so building a roster of singers adds up.
Synthesizer V is a one-time purchase (free Basic, $79 Pro), far cheaper over time than subscription vocal tools like Vocaloid's monthly plans or cloud-based services. It's ideal for hobbyists and indie producers; larger studios may prefer higher-end alternatives with more voice banks or per-track licensing.

About Synthesizer V
Synthesizer V is an AI-powered vocal synthesizer by Dreamtonics. You input notes and lyrics, and the deep-learning engine generates a vocal performance with natural, expressive timbre. The free version (Basic) covers core synthesis and basic pitch/vibrato/dynamics/timing edits. The paid Pro edition adds cross-synthesis blending, formant shifting, gender control, manual parameter automation, and Expressive Emotional Voice (EEV) support. Optional voice banks, sold separately, capture specific singer timbres. Supports English, Japanese, Chinese, Korean, and more. Integrates with your DAW via VST3, AU, and AAX plugins. Built for musicians, producers, and hobbyists who need quick vocal demos or full vocal tracks without hiring a singer. Compared to Vocaloid, Synthesizer V is often praised for its naturalness and ease of use, though its voice library is smaller. It's a strong pick for controllable, realistic vocals in production—just not for live performance or replacing a human vocalist for highly interpretive singing.
Behind the Verdict
Synthesizer V excels at turning written lyrics and melody into believable vocal performances. The core engine produces surprisingly expressive results with natural vibrato and dynamics, and the free Basic tier is generous—you can explore the full synthesis workflow without paying. For a one-time $79, Pro unlocks cross-synthesis (blending two voices), formant shifting, gender control, and manual automation of pitch and loudness, which gives you deep control over the final take. The EEV option adds a more emotionally nuanced voice, a nice upgrade for ballads and dramatic tracks. Voice banks are sold separately (typically $50–$100 each), so factor that in. The software runs as a desktop app with VST3/AU/AAX plugins, so it slots into your existing DAW. Multi-language support (English, Japanese, Chinese, Korean) is a plus for global producers. Limitations: the free version includes only one default voice bank, and the AI can struggle with fast, complex passages or non-standard vocal styles. There's no public API, so automation is limited. Compared to Vocaloid, the voice library is smaller, but the realism and ease of use are winning. Best for music producers, VTubers, and hobbyists. Avoid if you need live performance or expect a plug-and-play replacement for a human singer.

Featured Head-to-Head Comparisons
Synthesizer V vs Landr Mastering
Choose LANDR Mastering if you need fast, affordable mastering for finished tracks. Choose Synthesizer V if you need to generate realistic vocals from scratch. They solve entirely different problems – one polishes the final mix, the other creates vocal content. Most users who need both would use Synthesizer V first, then master with LANDR.
Synthesizer V vs Splice
If you need royalty-free samples across genres and want to rent-to-own premium plugins like Serum 2, Splice is the clear choice with its massive library and recent DAW plugin beta. If you need realistic AI singing vocals from lyrics, Synthesizer V is unmatched, but expect to buy voice banks separately. For most producers, Splice offers broader utility; for vocal-centric projects, Synthesizer V is essential.
Synthesizer V vs Storyfile
Not competitors – StoryFile is for authentic human video avatars in exhibits and legacy, while Synthesizer V is an AI singing voice tool for music production.
